In addition, it introduced the constitution and the working principle of the chain tension controller; which offered technical support for reliable operation of the scraper conveyor.Keywords : scraper conv eyor; chain tensi on; con trol tech no logy煤礦井下工作面開采實踐證明,刮板輸送機刮板鏈的張緊程度直接影響輸送機 的運行可靠性。刮板鏈過度松弛,會引起刮板鏈的堆舂與刮卡,易發(fā)生斷鏈事 故;刮板鏈張緊力過大,會加劇刮板與中部槽的磨損,輸送機無用功率增大, 降彳氐輸送機的使用壽命1。因此,刮板輸送機需要對刮板鏈的張緊力進行控制, 使其在適度張緊狀態(tài)下運行。
